FS-400 Series –

General Purpose, 90° Flow Path

Flow Rate Settings: Fixed Version: 0.75 GPM to 10.0 GPM

Port Size: 3/4˝

Primary Construction Material: Bronze

Setting Type: Fixed or Adjustable

Provides accurate flow detection in water and oil with 1% repeatability. Flow settings

on the adjustable version can be easily changed without disassembly. A shuttle by-

pass vane inside the housing is controlled externally using an ordinary flat-blade

screwdriver. These switches are ruggedly constructed of non-corrosive materials and

resist shock and vibration. Suitable for triggering alarms on interlocking shutdown

circuitry when flow rate is improper to protect bearings, gears and cooling systems.

Notes:

1. Flow settings for Fixed Version are calibrated using water at +70°F on increasing flow, with units in a

2. Adjustable units that are set to customer specifications are subject to GEMS test stand accuracy.

3. Use of 150 micron filtration is recommended.

4. Minimum 5 PSI line pressure required.
